Why does the ipad pro keyboard caps lock key changes language
I just brought the keyboard for ipad pro two weeks ago, the caps lock key was fine. But after i updated my ipad to ios10, the caps lock key stopped working. It now changes the language instead of switching caps.

If any one else has this problem, try going to "Settings, keyboard, Hardware keyboard (with smart keyboard attached) - ensure CapsLock switch to/from Latin is unticked"
Hopefully that helps
